The under-sea network targets on providing Internet facility under the seas and oceans. But it still remains a very controversial topic whether or not it would be a part of 6G networks. This network system involves optical and acoustic communication, and radio frequency. But the difficulty lies due to the unpredictability of the underwater environment, challenges that are to be faced, and the risk factors as water exhibits different propagation properties which are different from that of aerial or terrestrial terrains. Therefore, a lot of issues are yet to be resolved for under water 6g networks [1]}, [2]}.
